SPC Dec 7, 2021 0700 UTC Day 2 Convective Outlook

SPC 0700Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1132 PM CST Mon Dec 06 2021 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms appear unlikely across the contiguous United States on Wednesday. ...Synopsis and Discussion... Isolated to widely scattered thunderstorms will probably be ongoing at the start of the period across parts of the Southeast in a modest low-level warm advection regime. Due to a prior frontal intrusion into the northern Gulf of Mexico, the bulk of this morning convection is expected to remain elevated, with only weak MUCAPE forecast. As a large-scale upper trough progresses quickly eastward across the eastern CONUS through the day, these thunderstorms will likewise move off the Atlantic Coast. Latest guidance is in general agreement that modest low-level moisture will be in place across parts of north FL and southern GA ahead of a reinforcing cold front. Some potential for surface-based thunderstorms may exist across this region Wednesday afternoon. But, poor low-level convergence along the front as low/mid-level winds quickly veer to westerly and particularly poor mid-level lapse rates should tend to limit overall thunderstorm coverage and intensity. ..Gleason.. 12/07/2021 Read more LIVE:
